2004 Kia Sorento Cruise Control Problems

While driving, you heard a clunking noise and felt your truck shift. When you pulled over to investigate, you discovered your rear lower arm had fallen off the subframe due to corrosion from heavy salt exposure in Wisconsin. You had to have the vehicle towed home. The repair will likely involve replacing the corroded rear lower control arm and inspecting the subframe for further rust damage.

Your car drives normally, but then suddenly accelerates on its own even though your foot position on the gas pedal hasn't changed. This unpredictable acceleration could make the vehicle difficult to control. The issue may involve the throttle control system, fuel injectors, or engine computer needing inspection or replacement.

Your engine's RPM would randomly jump between 1,000 and 2,000 without you touching the accelerator, happening both while driving and sitting at red lights. The cruise control system was activating on its own without any indicator light showing it was on. Replacing the IAC valve didn't fix it, but disconnecting the cruise control cable at the throttle body stopped the problem completely.
